You are correct. There is no Camera Roll anymore as of iOS 8. Before iOS 8, there was a separate folder for Camera Roll and for Photo Stream, and a folder for Videos. The Shared and the Photos views were much as you see them in iOS 8.
With iOS 8, a design decision was made by Apple to combine the Photo Stream and the Camera Roll, and to make them act the way that the Photo Stream acted in iCloud prior to iOS 8. Namely, that the most recent 30 days of activity for both (since if you were using Photo Stream, they were the same for any photos taken on the device itself), would now be kept in a new Album called "Recently Added". This now mimics the way that Photo Stream always acted in iCloud.
They also decided to add a new folder called "Recently Deleted" to accommodate the rising user demand for a way to retrieve photos either accidentally deleted, or ones that the user deleted and now wanted back.
They then decided to put anything older than 30 days in the existing structure found in the Photos view.
I can't be sure, but I believe this is staging for the future state of the way that photos will be handled in the Apple world - using iCloud Drive and moving away from locally imported photo activity to iPhoto. Because if you are familiar with iPhoto, this is the same structure that iPhoto imposes on imported photos by using Events.
I'm also sure that many people are dismayed with this direction, but as I stated in the previous post, it is the direction in which Apple (and pretty much every other technology company) is moving.
There is no fix or workaround for this as it is not a bug or issue, it is a design decision that was implemented with intent. In my previous posts I was simply suggesting ways that you might be able to make that design decision work for you. That is the only "workaround" at the moment.
The more people who express their dismay to Apple (in constructive and definitive ways) the more likely it will be that Apple will at least look into a solution that will address those concerns (after all, the addition of the Recently Deleted Album was exactly that kind of response from Apple to users who were extremely unhappy that Apple provided no way to "undo" a deletion of a photo or photos from the Camera Roll).
So, again, I would suggest that you share your concerns and consternation with Apple. The more people who speak up, the more likely it is that a solution will, at least, be considered:
Apple - Feedback
